Item 1. Security and Issuer

This Amendment No. 2 to Schedule 13D (the “Statement”) supplements and amends the Statement on Schedule 13D of OrbiMed Advisors LLC, OrbiMed ROF II LLC, and OrbiMed Capital GP IV LLC (the “Statement”) originally filed with the Securities and Exchange Commission (the “SEC”) on August 18, 2020 as amended by Amendment No. 1 thereto filed with the SEC on July 14, 2021 (“Amendment No. 1”). This Statement relates to the common stock, par value $0.001 per share (the “Shares”) of Acutus Medical, Inc., a corporation organized under the laws of Delaware (the “Issuer”), with its principal executive offices located at 2210 Faraday Ave., Suite 100, Carlsbad, CA 92008. The Shares are listed on the NASDAQ Global Select Market under the ticker symbol “AFIB”. Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable.

On August 23, 2021, the Issuer entered into an exchange agreement with each of OrbiMed Private Investments IV, LP (“OPI IV”) and OrbiMed Royalty Opportunities II, LP (“ORO II” and, together with OPI IV, the “OrbiMed Funds”), pursuant to which, on such date, OPI IV exchanged 2,795,886 Shares for 2,795.886 shares of the Issuer’s Series A Preferred Stock and ORO II exchanged 1,105,114 Shares for 1,105.114 shares of the Issuer’s Series A Preferred Stock.

The terms of the Series A Preferred Stock (i) provide that each share is convertible into 1,000 Shares at the option of the holder thereof (but subject to the beneficial ownership limitation described below), (ii) provide that each share is entitled to a de minimis liquidation preference of $0.001 per share, (iii) provide that the shares would not have any voting rights, and (iv) otherwise be substantially equivalent to the Shares. The ability of a holder to convert Series A Preferred Stock into Shares is prohibited to the extent that, upon such conversion, such holder, its affiliates and other persons whose ownership of Shares would be aggregated with that of such holder for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, would exceed 4.9% of the total number of shares of Common Stock then outstanding (provided that this limitation could be increased to 9.9% with respect to a particular holder of Series A Preferred Stock at such holder’s election upon 61 days advance written notice to the Issuer (the “Ownership Cap”), although the Reporting Persons do not anticipate that such an increase would be applicable to shares of Series A Preferred Stock beneficially owned by the Reporting Persons). In connection with the exchange of the Shares for the Issuer’s Series A Preferred Stock, each of the OrbiMed Funds agreed that its outstanding warrants to purchase Shares would not be convertible to the extent that, upon conversion, the holder, its affiliates and other persons whose ownership of Shares would be aggregated with that of such holder for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, would exceed the Ownership Cap.

The information set forth in Item 1 of this Amendment No. 2 is incorporated herein by reference.

Item 4. Purpose of Transaction

The Shares acquired by the Reporting Persons were acquired for the purpose of making an investment in the Issuer and not with the intention of acquiring control of the Issuer’s business on behalf of the Reporting Persons’ respective advisory clients.

The Reporting Persons from time to time intend to review their investment in the Issuer on the basis of various factors, including the Issuer’s business, financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and those for the Issuer’s Shares in particular, as well as other developments and other investment opportunities. Based upon such review, the Reporting Persons will take such actions in the future as the Reporting Persons may deem appropriate in light of the circumstances existing from time to time. If the Reporting Persons believe that further investment in the Issuer is attractive, whether because of the market price of Shares or otherwise, they may acquire Shares or other securities of the Issuer either in the open market or in privately negotiated transactions. Similarly, depending on market and other factors, the Reporting Persons may determine to dispose of some or all of the Shares currently owned by the Reporting Persons or otherwise acquired by the Reporting Persons either in the open market or in privately negotiated transactions.

Except as set forth in this Schedule 13D, the Reporting Persons have not formulated any plans or proposals which relate to or would result in: (a) the acquisition by any person of additional securities of the Issuer or the disposition of securities of the Issuer, (b) an extraordinary corporate transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries, (c) a sale or transfer of a material amount of the assets of the Issuer or any of its subsidiaries, (d) any change in the present Board of Directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board, (e) any material change in the Issuer’s capitalization or dividend policy of the Issuer, (f) any other material change in the Issuer’s business or corporate structure, (g) any change in the Issuer’s charter or bylaws or other instrument corresponding thereto or other action which may impede the acquisition of control of the Issuer by any person, (h) causing a class of the Issuer’s securities to be deregistered or delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association, (i) a class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act or (j) any action similar to any of those enumerated above.

Item 5. Interests in Securities of the Issuer

(a) — (b) The following disclosure is based upon 34,607,593 outstanding Shares of the Issuer, as set forth in the Issuer’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 13, 2021.

In addition, OPI IV owns warrants to purchase 60,339 Shares, and 2,795.886 shares of Series A Preferred Stock that are convertible into 2,795,886 Shares.

OrbiMed Advisors exercises this investment and voting power through a management committee comprised of Carl L. Gordon, Sven H. Borho, and W. Carter Neild, each of whom disclaims beneficial ownership of the Shares held by OPI IV.

As of the date of this filing, ORO II, a limited partnership organized under the laws of Delaware, holds 572,247 Shares, constituting approximately 1.7% of the issued and outstanding Shares. In addition, ORO II owns warrants to purchase 272,228 Shares, and 1,105.114 shares of Series A Preferred Stock that are convertible into 1,105,114 Shares.
